Brainwave real-time evaluation system and evaluation method thereof

Abstract

The invention provides a brainwave real-time evaluation system. The system comprises a core module, a parameter selection module, a characteristic extraction module and a display module, wherein the core module is connected with the parameter selection module in a wired or wireless communication mode and the characteristic extraction module is connected with the display module in the wired or wireless communication mode; and the parameter selection module is connected with the characteristic extraction module for selecting and extracting various data. In the brainwave real-time evaluation system, the characteristic extraction module is a sensor and is used for extracting various signals and transmitting the various signals to the core module. The system has the advantages of quantitative determination, real-time evaluation, individual pertinence, wide application value, precise determination result and high universality; and the working efficiency and the consistency of an analysis result are improved.

Description

technical field [0001] The invention relates to a brainwave real-time evaluation system and an evaluation method thereof. Background technique [0002] With the rapid development of society, there are more and more sub-healthy people. Fatigue research and relaxation therapy are of great significance. It is particularly important to analyze and study brain waves and their evaluation standards. [0003] Relaxation training refers to completing a specific action program according to certain requirements in a quiet environment. Through repeated practice, people learn to consciously control their own psychophysiological activities, so as to reduce the body's arousal level and adjust the stress caused by tension. The disorder of the body's psychological-physiological functions caused by stimulation. [0004] Quantitative determination of fatigue and relaxation training: an EEG study. At present, subjective evaluation methods and behavioral description methods are mainly used to ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of brain wave real-time evaluation system and its evaluation method, to solve the problems in the background technology that the quantitative analysis of mental fatigue and relaxation training cannot be carried out, the real-time performance is poor, and the individual pertinence is not strong; the application of power spectrum analysis and The principal component analysis method solves the problem of extracting EEG signal features, successfully extracts comprehensive indicators closely related to human fatigue and relaxation, and uses support vector machines to efficiently classify brain states in the principal component space, improving the accuracy of interpretation In addition, a brain wave real-time evaluation system and its evaluation method provide the possibility for users to independently perform relaxation training and training evaluation in home and office environments
